Chemistry is the experimental and theoretical study of materials on their properties at both the macroscopic and microscopic levels.In a patent， Product Details of 2008-75-5, Which mentioned a new discovery about 2008-75-5
The present invention relates to a novel process for the preparation of heterocyclic alkylamide derivatives having the following formula: STR1 and the pharmaceutically acceptable acid addition salt thereof wherein X represents halo, alkyl having 1 to 6 carbon atoms, hydrido, trifluoromethyl, phenyl, or lower alkoxy having 1 to 6 carbon atoms; Y represents the group –CN or –CONH2 ; R2 represents alkyl having 1 to 6 carbon atoms; R3 represents acetyl, benzoyl, phenacetyl or trifluoroacetyl; m is the integer 1 or 2 and n is an integer from 1 to 3 inclusive; which comprises alkylating an aminoalkanol using a benzaldehyde/aminoalkanol/ketone mixture in the presence of a platinum catalyst to give an alkyl substituted phenylmethylaminoalkanol; halogenating the alkanol using a halogenating agent to give a haloalkyl alkylbenzenemethanamine salt; treating the salt with substituted phenyl piperidinealkanenitrile or substituted phenyl pyrrolidinealkanenitrile in the presence of base and dimethyl sulfoxide to give a substituted phenyl substituted aminoalkyl piperidinealkanenitrile or substituted aminoalkyl pyrrolidinealkanenitrile; hydration of the nitrile to give the corresponding amide; and N-debenzylation of the amide followed by acetylation to give the compounds of formula I wherein Y is –CONH2.
